Mode selection
The auto reclosing mode is selected with the setting ARMode. As an alternative to
the setting, the mode can be selected by connecting an integer, for example from
function block B16I, to the MODEINT input. The six possible modes are described
in Table 176 below with their corresponding MODEINT integer value.
When a valid integer is connected to the input MODEINT the selected setting
ARMode will be invalid and the MODEINT input value will be used instead. The
selected mode is reported as an integer on the MODE output.
Please note that tripping mode of the IED is defined in Trip Logic function block
SMPPTRC. For example for two-phase faults either 2ph or 3ph tripping and
consequent auto reclosing can be selected
